my viewpoint of Michael Fremer and Jacob Heilbrunn dart impressions are direct to me from them. which their writings are true to. of course, they are just 2 guys with opinions. like the rest of us have.
maybe in your experiences it's not always like that. which is fair.
IMHO the voices of reviewers are something to be heard however they are opinions based on their likes and experiences. Since only a few have had the opportunity to actually hear their systems in their rooms the rest is highly speculative. I take all shows with a grain of salt as NONE of them ever came close to what a proper set up in a mature purpose built room can accomplish. I can get a glimpse or an idea of something and perhaps that will make me look deeper but I have NEVER had my socks blown off at any show.
Systems are just that. Dependant of the room, the gear and the set up. No speaker is perfect for everyone not even my own ( Oliver I am kidding LOL) The interaction of electronics, speakers, cables, source and the room is what we hear.We all have to work with what we have chosen.
If you picked a room and a speakers then that is your anchor and you need to live and die with that unless you start over in a another space or with another speaker.
The brands mentioned here are all well respected. My choice for the one I own and have spent time with is the CH 10 series both amp and preamp. IMO its the most satisfying of what I have lived with, tried or owned.I have spoken with RK he seems to bne a very good guy but getting to hear his stuff in the US is just about impossible. DartZel is not easily findable either but a lot easier than RK. I have not had them in my system but have listened extensively to them and I think they are wonderful products cant tell you if I would prefer them to what I own and to be honest I am not looking. I have tried many others over the last period of time DAG, Soulution, Griffen not Apex, Spectral, ARC, CJ VAC and others. I picked got mine and stand by that decision. Argueing IMO in a vacuum is really not productive.
One last thing the reviewers dont all access to the same gear as well. RH, JH,JV all are from TAS yet they don't have the same gear and I doubt they even listen to each others or certanly not often.
Best advice pick the speaker you love and that can work in your space or make a space where it can work. The rest will follow suite and a survey really wont get you there only doing the work and learning will. I seriously doubt , actually know, there is no universal answer. No amplifier etc. that will work equally well on every speaker design and room. This I have learned over 50 years.
